Cleaning black wheels

goodmorning everyone. Need suggestions or advice from possible previous experiences. These wheels don’t look too hot, any suggestions on how to help that. Thanks !

 

I had the same issue when my son drove my truck for 2yrs while off at school. They came back faded and chalky. I washed them with soap and water, then sprayed them down with some paint prep (in a rattle can) and finally used some matt high temp clear coat also from a rattle can. came out as good as new. The paint prep spray may not be necessary.

 

Thank you for your reply. Have a nice day.
